Data Submission Resources
In addition to hospital data for each inpatient discharge, outpatient observation stay, and emergency department visit in Massachusetts, CHIA collects certain Electronic Health Record Data (EHRD). This data is shared with MassHealth in an Enhanced Demographics Data File in support of the MassHealth health equity program.
Data files must be submitted quarterly to CHIA according to the following submittal schedule:
New users must register to submit data via CHIA Submissions.
For help with registration, email DL-Data-Submitter-HelpDesk@chiamass.gov or call 617-701-8100 (9am-5pm Monday through Friday).
Email all questions and comments about EHRD collection to hospitaldata@chiamass.gov.
CHIA will continue to collect sexual orientation/gender identity (SOGI) patient data reported in the fields below but will not be sharing this information with MassHealth for individuals younger than 19 years of age as of December 31 of the measurement year. This change does not affect the EHRD File Submission Guide.
